灰色预测的二次拟合，数据要自己改一下，其他的可以通用(Quadratic fit of the gray prediction)

对声音信号进行butter低通滤波,对录入的信号进行傅里叶变换，同时对比滤波前后，声音信号的不同(Butter sound signal low-pass filtering, of the Fourier transform of input signals, while before and after filtering, different sound signal)

este es un fitro paso bajo y paso alto muy conveniente para el uso en ingenieria electronica y mas aplicaciones

利用x(n)=Asin(pi*n/16)+z(n),z(n)为mean=0，var=0.1高斯白噪声，x(n)的SNR为10dB,s(n)=Asin(pi*n/16-5*pi),得出了x(n)和s(n)互相关函数r(n)，以及二者的卷积和.(The utilization for the mean of x (n) = Asin (pi* n/16)+ z (n), z (n) = 0, var = 0.1 Gaussian white noise, x (n) is the SNR as 10dB, s (n) =Asin (pi* n/16-5* pi), draw the x (n) and s (n) the cross-correlation function r (n), as well as the convolution of the two.)
